The air dryer cartridge in your Tiffin Allegro bus is one of those components that doesn’t get much attention until your air brakes start acting up. I’ve replaced plenty of these over the years, and I can tell you the difference between doing it right and doing it wrong is night and day. Here’s what … Read more

How much heat can you afford to lose on a freezing night when your Cornerstone’s furnace won’t ignite? That’s the question staring you down right now—and the answer is none.

It was November, maybe fifty-two degrees outside, and I’d cranked the thermostat to heat mode expecting the familiar low rumble of the Jayco’s furnace catching. Instead: click. Click. Click. Then nothing. No roar, no warmth building in the ducts, just that hollow, repeating tick that told me the igniter was cycling without actually firing the … Read more

Most Winnebago Forza owners assume their rooftop AC will soldier on indefinitely—that it’s built to last as long as the diesel engine underneath. That assumption costs people money, comfort, and peace of mind.

I’ve got my workbench set up in the shade behind bay two, and sitting on it right now is a Dometic AC shroud I pulled off a Thor Palazzo last week. The owner called me at 2 PM on a Saturday—kids playing in the background, wife asking what was wrong—because the unit had quit mid-afternoon. … Read more
